Dannii Minogue has hinted that rumours of a duet with sister Kylie may be true.
Yesterday it was reported that the Australian pop sisters had teamed up for a cover of Abba's 'The Winner Takes It All', to be used as the theme tune for new BBC sitcom Beautiful People.
When asked about the rumoured duet at today's X Factor press launch, Dannii smiled broadly before gesturing that her lips were sealed on the matter.
Her fellow X Factor judge Louis Walsh noted: "That means a yes!"
The Minogue sisters have never previously recorded a duet together, but Dannii joined Kylie onstage for a rendition of 'Kids' during her sister's 'Showgirl - Homecoming Tour' in 2007.
